     1. The   Safety Director of Honda USA took samples at random from the file of minor   accidents and classified them according to the time the accident took place.   The sample data is as follows: 8am to 9am 6 accidents 9am to 10 am 6   accidents 10am to 11 am 20 accidents 11am to noon 8 accidents Noon to 1pm 7   accidents 1pm to 2pm 8 accidents 2pm to 3pm 10 accidents 3pm to 4pm 6   accidents At the 0.01 level of significance, are the accidents evenly   distributed throughout the day?    

     2. For   many years TV executives used the guideline that 30 percent of the audience   were watching each of the prime-time networks and 10 percent were watching   cable stations on a weekday night. A random sample of 500 viewers in the   Tampa-St. Petersburg area last Monday night showed that 165 homes were tuned   in to the ABC affiliate, 140 to the CBS affiliate, 125 to the NBC affiliate,   and the remainder were viewing a cable station. At the 0.05 level of   significance, can we conclude that the old guideline is still reasonable?
